IMPROVEMENT IN MECHANISMS FOR SETTING AND FINISHING SHOE-SOLE EDGES.

Specification forming part of Letters Patent No. 219,442, dated September 9, 1879; application filed June 25, 1879.

To all whom it may concern:

Be it known I that I, LORENZO SMITH BRIDGES, of Woodville, in the county of Middlesex and State of Massachusetts, have invented a new and useful Improvement in Mechanisms for Setting or Finishing Shoe- Sole Edges; and do hereby declare the same to be described in the following specification and represented in the accompanying drawings, of which- Figure 1 is a side elevation, Fig. 2 a longitudinal section, and Fig. 3 is an end view,

' part edge-setters is arranged, turned down, of

less diameter than the rest or part b, there being at the junction of the two parts a and b a shoulder, c, as shown. The part a at its outer end is provided with a screw, (1, upon which is screwed the shank or carrier 6 of a sole-shank edgesetter, B, formed and arranged as shown. The said carrier 0 serves not only. to support the shankfedge setter, but as a nut to hold, with the shoulder a, the set or series of fore-part setters O D E firmly in place in the arbor.

Each of the said setters not only varies in width, but in diameter, with respect to that immediately next to it-that is to say, the beddisk f of the second setter, l), is not only a little greater in diameter but wider than the bed-disk f of the setter (J. The same may be said with respect to the bed-disk f of the setter E relatively to the bed-disk f Furthermore, the flange or flangedisk g between the two bed-disks f and f has a diameter greater than that of the first or end flange or flange-disk g. The flange-disk g has a diameter greater than that of the flange disk g and less than that of the end flange-disk, 9

Were each of the flanges or flange-disks of the composite edge-setter alike in size or made with their diameters equal to each other, and were each of the bed-disks so made, though varying in width, the composite edgesetter could not be used to advantage, because in attempting to use either of its second or third setters the upper of the shoe would be liable to be forced or carried into contact with the periphery of the flange of the next adjacent setter, and in consequence thereof to be creased or injured thereby.

To prevent such injury to the upper from taking place I make not only the bed-disk, but the flanges or flange-disks, to vary or increase in diameter relatively to each other in manner as represented, in which case it will be seen that in forcing a shoe-sole against the second or middle bed-disk the flange-disk g will enter the space between the sole and the upper; but the flan ge-disk g, by being less in size than the disk 9, will not touch the shoeupper while the arbor and the series of edgesetters may be in revolution. So in forcing the sole against the largest bed-disk the flange or flange-disk by having a diameter less than that of the disk 9 will not touch or be liable to touch the upper.

I would remark that the sole-shank edgesetter is to be used with each of the fore-part edge-setters in finishing the edge of a shoe or boot sole; all of which will be easily understood by shoemakers.

What I claim as my invention is as follows: A composite fore-part edge-setter, substantially as described, consisting of a series of two or more separate beds or bed-dislks,ff f varying in width and diameters, as explained, and a series of separate flanges or flan ge-disks, g g g therefor, arranged therewith and Varying in their diameters, substantially as set forth, all ofsuch disks and flanges being arranged with each other and combined with an arbor. essentially in manner as represented.
